Got an email from Uprev about VVEL:

VVEL control isn't something people are going to want to jump into. If you break anything in the VVEL system, expect to spend $10k+ with Nissan as they are the single and only source for those parts. They only sell VVEL parts as a pair of complete head assemblies. So if anything breaks your minimum out of pocket expense is $10k+

Looks like they view VVEL as a non-seller and potentially a high risk part of tuning.
